I am installing SSL certificate in my CentOS 6. In order to do that, I have to setup firewall rule.
But when I am setting up the firewall I get an error:
$ firewall-cmd --permanent --add-service=https
-bash: firewall-cmd: command not found.
It appears that only the command iptables
works in CentOS 6.
I also tried to install firewalld using the command
$sudo yum install firewalld.
But it gives me the followingerror:
No package firewalld available.

Firewalld is only part of CentOS 7. It does not ship with, and afaik is not available for, CentOS 6. If you really can't face dealing with
iptables
rules (which I personally feel are not all that difficult), some people feel thatsystem-config-firewall
is an acceptable substitute.Or just try
though depending on your existing ruleset, this may or may not play well.
